Frd No 20, located in Mitchell, Kansas, is a local government-owned earth dam designed by the USDA NRCS for flood risk reduction on the Salt Creek-TR river. Completed in 1982, this dam stands at a height of 41.8 feet with a length of 600 feet, providing a storage capacity of 1096.2 acre-feet and a drainage area of 3.61 square miles. Despite its low hazard potential, the dam's condition assessment is currently not rated.

While Frd No 20 does not have any associated structures or outlet gates, it features an uncontrolled spillway with a width of 40 feet. The dam's primary purpose is flood risk reduction, aligning with its design for buttress core types and unlisted/unknown foundations. With a normal storage capacity of 167.3 acre-feet, the dam serves as a crucial infrastructure for managing water resources in the region, with a moderate risk assessment rating of 3.

As a regulated structure under the jurisdiction of the Kansas Department of Agriculture, Frd No 20 undergoes state permitting, inspection, and enforcement to ensure its operational integrity. With its location in the Kansas City District and under the supervision of the Natural Resources Conservation Service, this dam plays a vital role in mitigating flood risks and protecting the local community from potential water-related hazards.
